摘要:
A plasma-display panel of high luminosity and efficiency which does not require auxiliary cells so that the panel structure has high-density cells, enabling longer emission time and smaller reactive power. A driving method of such a PDP comprising a first insulator substrate and a second insulator substrate which is arranged at a given distance above the first insulator substance; the first insulator substrate having a first line electrode group and a second line electrode group which are parallel, and the second insulator substrate having a third line electrode group which are parallel to the first and the second line electrode groups so that the third line electrode group and the first and the second electrode groups appear to form a two-dimensional lattice when viewed from above; thereby forming a discharge space between the first and the second insulator substrates; the first and the third line electrode groups having parts exposed to the discharge space, while the second line electrode group being covered by dielectric layer in the discharge space. The method comprises: writing image information by addressing discharge between the line electrode groups which appear to form a two-dimensional lattice when viewed from above and accumulating charges on the dielectric layer; and floating the charges in the discharge space by applying an auxiliary pulse voltage below discharge voltage to the second electrode group, and generating direct current discharge by applying a sustain pulse voltage in-between the first and the third line electrode groups.
摘要:
Set-up, write, sustain and erase pulses are variously applied to a plasma display panel using a staircase waveform in which the rising or falling portion is in at least two steps. These staircase waveforms can be realised by adding at least two pulses. Use of such waveforms for the set-up, write and erase pulses improves contrast, and use for the sustain pulses reduces screen flicker and improves luminous efficiency. This is of particular use in driving high definition plasma display panels to achieve high image quality and high luminance.

When a gas discharge panel is driven, a voltage is applied between scan and address electrode groups to perform set-up. The voltage waveform has four intervals. In a first interval, the voltage is raised in a short time (less than 10 µs) to a first voltage, wherein 100 V ≤ first voltage

摘要:
A plasma display panel (PDP) driving method is disclosed for a PDP in which a plurality of discharge cells are arranged between a pair of substrates (11,12), the method repeating a number of steps to perform image display. One of the steps is a set-up step for applying a set-up pulse to each of the plurality of discharge cells to accumulate charge in each discharge cell. The set-up pulse is a staircase waveform which either rises or falls in at least two steps. For a rising waveform, the voltage jump for the first-step rise is no less than V f -70V but no greater than V f , where V f is a discharge voltage. For a falling waveform, the ratio of a first-step voltage fall (V 1 ) to a peak voltage (V st ) is no less than 0.05:1 and no more than 0.8:1 and the ratio of (a) a time (t p ) form the end of the first-step fall to the start of the second step-fall to (b) pulse width (t w ) being no less than 0.05:1 and no more than 0.6:1.
